I was already writing about the necessity of reptiles of regular sunbathing due to their inability to produce their own heat internally. Reptiles need to obtain heat from the environment. Having a pet reptile such as a turtle, a bearded dragon or snakes you need to provide heat sources for this reason.
There is something else you will need to provide your pet reptile that‘s as vitally essential as heat. That is light. Light emitting UVB as a matter of fact. Why does your pet reptile need UVB light and what exactly is that?
